DIY PSU Installation

Today I have to uninstall the faulty six-years old power supply unit (PSU) in my old Pentium III PC so that I could install a relatively-new-yet-old power supply which currently works only half of the time. What I plan to do is buy a branded power supply unit with twin fan for my Pentium 4 PC and replace the semi-faulty power supply in my Pentium III computer so that every power-related problem I have with my PC will be resolved. I run my primary PC 24/7 so I have to buy a reliable power supply geared towards the overclocker enthusiasts to avoid heat problems resulting to abnormal shutdowns.

I\’m quite hesitant at the moment because I\’m deciding to buy an Enermax EG465P-VE (430 Watts) power supply. At the moment, I have a generic 350 Watts PSU which is not enough according to my experience. Even though my PC is quite aged already, collectively I have 5 fans to keep the system cool including the fan for graphics card, the chip set and the processor. I also have one extra fan at the side of the casing and an exhaust system fan at the back of the tower casing. Include my devices that hooks to my USB ports — printer, scanner, mouse, and occasionally my flash disk and Nokia phone cable — that\’s already 5 devices. Inside, I have an integrated 10/100 LAN card, integrated sound card, Radeon 9550 256 MB video card, 1 Gig DDR memory and an \”extension\” card containing firewire and additional USB ports. I run 2 hard disks, a DVD-writer and a floppy drive which I have not used for almost 3 years. I may plug in more devices in the future so to make my upgrade future proof, I think that a 430 Watts PSU would be the right choice. I have read very good reviews about Enermax and it seems to be the most available PSU in my favorite PC shop.

Why do I have to do all these? Well, first of all, I want to transfer the current PSU in my primary PC to my old PC to replace the PSU it has, yet again. Secondly, I do not want my PC to restart every day due to heat problems. I care for the integrity of the data in PC because some of them are really precious to me. I have created back ups but it\’s too troublesome to find out one day that my PC is clinically dead due to power supply issues. I do not want that happening to me since I do not have much time for PC repairs during weekdays.

Perhaps I will buy my new PSU on my next salary and I\’ll post a review about it after I have used it continuously in a week.

Btw, the main reason I am hesitant to buy the Enermax PSU even though I\’m almost ready to buy it is because of the price… I\’ll have to shell out 4k just for the unit. I should have been saving up for PS3, not PSU! x_x
